One of the main cons with electric cars is the storage of electricity that moves. Batteries are not saved as much electricity to make long journeys, which determines that in order to travel more miles, you have to put more batteries. Nevertheless the use of these cars is one of the goals that humanity must be imposed to combat global warming, as fossil fuel combustion accounts for much of the emissions of greenhouse gases into the atmosphere. So to make a viable electric car is really organic, not only have to get better batteries, but feed them with renewable energy.

In Germany they are betting to get a million electric vehicles powered only by renewable energy by 2020. They also hope that in this term green electricity account 30 percent of the country’s energy consumption. The problem faced is that it is difficult to achieve a goal such as electromovilidad is completely organic. There is also the danger that, if the electric car industry is growing faster than renewables, which will lead to increased energy consumption to be covered with clean energy, so electric cars would still pollute, but a lesser degree than burning fossil fuels.

To deal with this while achieving the goal, Dominik Noer, the Fraunhofer Institute for Solar Energy, has developed a smart grid system. It is based on electric cars with a capacity to store much energy. Assuming that the cars are usually parked 20 of the 24 hours a day, is that enough time to reload if they are electric, using peak electricity from wind or solar energy, and also when energy demand is lower, so as not to affect the peak hour power consumption.

This intelligent charging system could help inject demand for electric cars to the electricity network is not saturated at peak hours. The system of smart charging stations is a device that allows electric cars recharged when renewable energies are at their peak of energy injection to the network. Thus, not only avoid the rush hour recharge, but making full use of peak wind and solar, which is sometimes wasted. Wind and solar are dependent on wind and sun, respectively, and therefore sometimes have their maximum peak power production just as demand is lower, making that energy is lost as it can not be stored. With the advent of electric cars, and with this intelligent charging system, could exploit this extra wasted.

The initiative also is betting that the recharge is charged less at the time of peak of renewable generation, and more expensive during peak hours of consumption. Benefits should be given instead of cons to encourage the use of electric cars.

General Motors Vice Chairman: Company Dell Latitude D620 Battery electric vehicle batteries overheating problem would not exist

General Motors Corporation (General Motors Corp) Vice-Chairman Lutz (Bob Lutz), said General Motors for its electric vehicle battery technology, “hundred percent confident” will not encounter Toyota Motor Corporation (Toyota Motor Corp) produced by cells overheating.

Lutz said that if this type of Dell Latitude D820 Battery technology development can be successful, not sure whether it’s electric vehicles than Toyota, there is a great advantage in terms of time.

Lutz Motor Show in Frankfurt, said before a news conference, if such cells can be a good way to work, each auto manufacturer will use it.

Toyota hybrid cars for its next-generation lithium-ion sony vgp-bpl9 battery process has been slowed down due to overheating problems.

GM is currently being used in lithium batteries use different ingredients.

Lutz said the sony vgp-bps9 company is very confident that such batteries do not output overheating.

Lutz also said GM will be in a number of months or a year with better electric car beat Toyota in the market, it is expected that such advantages do not last long.

Lutz said, “Toyota will also have this technology, every car manufacturer will have this sony vgp-bpl8 technology.”

The composition of electric vehicles, including electric drives and control systems, power transmission and other mechanical drive system, complete installation tasks. Power driver and control system is the core of electric vehicles as well as internal combustion engines of motor vehicles from the largest difference. Power driver and control system by the drive motor, power supply and motor speed control device and so on. Electric vehicles equipped with the basic and the other the same internal combustion engine vehicle.

2.1. Of electric vehicles, electric power cars

Power for electric vehicles, electric cars provided by the drive motor power, motor power of the mechanical energy into electrical energy through the direct drive gear or wheel and the work device. At present, electric vehicles on the most widely used lead-acid laptop battery power source is, but with the development of electric vehicle technology, and many are developing new type of battery. These power supply (batteries) are mainly sodium sulfur batteries, nickel-chromium batteries, lithium batteries, fuel cells, flywheel batteries, etc. Application of the new power supply for the development of electric vehicles has opened up broad prospects.

2.2. Of electric vehicles, electric cars drive motor

The role of motor-driven power supply is the mechanical energy into electrical energy through the direct drive gear or wheel and the work device. At present, electric vehicles, electric cars on the widely used series-excited DC motor, this motor has a “soft” mechanical properties, and the car is very consistent with the traffic characteristics. However, due to the existence of DC motor commutation spark power than smaller, less efficient, maintenance workload, with the electric motor control technology and technological development, it is bound to gradually brushless DC motor (BCDM), Switched Reluctance Motor (SRM) and replaced by the exchange of asynchronous motor.

2.3. Of electric vehicles, electric car motor speed control device

Motor speed control device for electric vehicles, such as variable speed and direction of change set, its role is to control the motor voltage or current, the completion of the drive motor torque and the control of rotation direction.

Early electric cars, electric cars, electric cars, electric cars using DC motor speed control or change the electrical series resistance of the magnetic field coil turns to achieve. Because there is a level of speed and will produce additional electrical energy consumption or use of the structure of the complex, it is now seldom used. At present, the application of electric vehicles is a wider range of speed control thyristor chopper through the uniform change of the terminal voltage motor control motor current, to realize stepless speed regulation motor. In the electronic power of the continuous development of technology, it also gradually by other power transistor (into the GTO, MOSFET, BTR and IGBT, inspiron e1505 battery etc.) to replace the chopper speed control devices. From technology development, along with the application of the new drive motor, electric vehicles into the speed control of DC Inverter technology, will become the inevitable trend.

Electric vehicles, electric cars in the drive to transform rotary motor control, DC motor armature to rely on contacts or change the current direction of the magnetic field, the spin motor to achieve the transformation, which makes circuit complexity, reliability, lower. When the exchange of asynchronous motor drive, the motor can turn to transform the magnetic field changes the phase sequence of three-phase current to enable simplified control circuitry. In addition, the use of AC motor and VVVF control technology, electric vehicles, electric cars the braking energy recovery control more convenient and more simple control circuit.
